Elementary and Intermediate Algebra

WEBASSIGN ONLINE COURSE SOLUTION provides support for you and your students. Fully integrated with this printed edition of the text, WebAssign offers both a powerful online homework and a course management system that engages students in learning math. Pre-built assignments (Course Packs), just-in-time remediation (Learn Its) and unique question types (Responsive Questions and Concept Checks) vetted by trusted subject matter experts help you foster a deeper understanding of course concepts.

THE LANGUAGE OF ALGEBRA BOXES draw connections between mathematical terms and everyday references to reinforce the language of algebra thread that runs throughout the text.

TEACHING TIPS have been placed at strategic places in the margins to offer instructional suggestions that can be employed during classroom presentations. In addition, each worked example has an accompanying "Teaching Example" that instructors can use as part of a classroom lecture.

STUDY SETS found in each section are designed for students to methodically build their knowledge of the section concepts, from basic recall to increasingly complex problem solving, through reading, writing and thinking mathematically. A typical "Study Set" includes the following problem types: Vocabulary, Concepts, Notation, Guided Practice, Try It Yourself, Applications, Step-By-Step, Find It, Writing and Challenge Problems.

DEEPEN ALGEBRAIC CONCEPT UNDERSTANDING with worked examples that use "Strategy" and "Why" explanations. Detailed author notes throughout the worked examples guide students along a step-by-step process. They are written in complete sentences to mimic what an instructor might say when he or she explains solution steps in front of the class. "Now Try" links to similar problems in the Guided Practice section of the Study Sets.

STUDENT SUPPORT for those with difficulty reading the mathematical notation of algebra. To provide students assistance, notes such as "Read as ..." statements, appear throughout the text to explain how to read newly introduced mathematical notations.

*NEW* UPDATED REAL-LIFE EXAMPLES with a multitude of new application problems that deal with current topics today’s math students might encounter in their everyday lives have been added.

*NEW* UNIQUE "STEP-BY-STEP" PROBLEM TYPE is available. It is designed to improve students’ ability to read and write the language of algebra. This instructional feature gives students all of the steps used to solve a problem and then determine the correct order.

*NEW* GROWTH MINDSET is encouraged by identifying errors in mathematical solutions. To promote a growth mindset, many "Study Sets" now contain "Find It" problems where students are asked to spot any errors, justify their reasoning and solve the problem correctly. "Find It" problems contain both conceptual and computational errors.

*NEW* SALARY FIGURES AND JOB OUTLOOK INFORMATION are updated in the "from Campus to Careers" chapter-opener features. Several new careers have been inserted such as physical therapy assistant, robotics technician, web designer, nurse practitioner and construction manager. Associated application problems for all of these vocations are included in the "Study Sets."

*NEW* MORE GRAPHS INCLUDED to communicate important quantitative information in a visual format. Knowing how to interpret graphs has become a crucial skill to have in the workplace. For this reason, many more graphs have been included in the "Study Sets" that call for students to do just that -- read and interpret a wide variety of graphs (and illustrations) of real-life situations.

*NEW* EYE-CATCHING CAUTION BOXES have been added to sections in Chapter 7 to stress the importance of factoring when simplifying rational expressions and solving rational equations.
